Find a fourth degree polynimial functionwith real coefficents that has -1,1and 3i as zeros, for simplicity let a=1(leading coefficent).Express the polynomial in standard form
\n" ); document.write( "---------------
\n" ); document.write( "The 4th zero will be -3i, they come in pairs.
\n" ); document.write( "It's (x-1)*(x+1)*(x+3i)*(x-3i) = 0
\n" ); document.write( "
\n" ); document.write( "
\n" );
